Burton "Gus" Guster is a fictional character on the USA Network television comedy Psych played by American actor Dulé Hill. He functions as the "straight man" for Shawn Spencer's antics, and provides sobering advice, helpful knowledge, steady support, and friendship. Over the course of the show, Gus evolves from nothing more than a conventional, uptight pharmaceutical representative to a strong support system through all Shawn Spencer's crazy antics. He frequently tries to pass himself off as "fearless" although in reality the opposite is true, and often cries, sometimes due to "sympathy" and other times when Shawn is insensitive to his feelings. It is believed that Gus was named after a relative of Steve Franks, the technical producer of the show, Burton Franks.
